Sun witnesses a massive explosion on April 23: How it will impact Earth
A rare "super-sympathetic" solar flare event, involving four powerful bursts of radiation, could launch a solar storm towards Earth, potentially causing disruptions to power grids, communication networks, and creating auroras at unusual latitudes.
Pune: Scientists at city-based National Centre for Radio Astrophysics-Tata Institute of Fundamental Research (NCRA-TIFR) have captured detailed images of Sun at radio wavelengths using the MeerKAT telescope in South Africa, which astrophysicists believe would open a new frontier in solar physics .The NCRA scientists said the radio emission from Sun provided several unique features to estimate different physical parameters of its corona (outermost part of Sun’s atmosphere), which were otherwise simply inaccessible.The images of Sun would enable a host of novel studies, while opening the door to a large unexplored phase space with significant discovery potential, they said.These observations were published in the Astrophysical Journal recently.Devojyoti Kansabanik, lead author of the study, said, “Sun is a surprisingly challenging source to study, especially at radio wavelengths. The radio emissions arise from the tenuous atmosphere of Sun, a region known as the corona and visible to the naked eye only during total eclipse. It is the birthplace of the phenomena that impact Earth’s environment.”The researchers developed algorithms to estimate and correct the effects of both the instrument (MeerKAT telescope) and its peripheral vision. Researcher Surajit Mondal, a part of the team, said, “After correcting all these effects accurately, the researchers captured the high-fidelity solar images.”The images of Sun published in the paper were made using only 15 minutes of MeerKAT observations on Sept 26 and 27, 2020. Researcher Divya Oberoi, who was also part of the study, “This will open a new frontier in solar physics.”
